摘　　要：为应对寒区隧道中心排水管发生冻害的问题,提出一种新型保温施工材料——竹缠绕基材中心排水管在寒区隧道中的应用研究。结合西北地区某隧道,采用现场温度监测试验及温度场数值模拟的方法,重点研究竹缠绕中心排水管在极值低温月份(1月)的温度变化过程。结果表明,竹缠绕基质隧道中心排水管具有良好的保温性能,不会因冻害而发生冻胀堵塞的现象。In order to deal with the problem of freezing damage in the central drainage pipe of the tunnel in cold regions,a new kind of insulation construction material,bamboo winding substrate central drainage pipe,was put forward.Combined with a tunnel in northwest China,the temperature change process of the bamboo winding center drainage pipe in the extremely low-temperature month(January)was studied by field temperature monitoring test and numerical simulation.The results show that:the central drainage pipe of the bamboo winding matrix tunnel has good thermal insulation performance and will not cause frost swelling and blockage due to freezing damage.
